Specification of Letters Patent.

Patented Aug. 29, 1905.

Application filed March 31, 1905. Serial No. 253,161.

To all whom it may concern.-

Be it known that I, SAHAG TERZIAN, a citizen of the UnitedStates,residing at St. Louis, State of Missouri, have invented certainnew and useful Improvements in Fan Driving Mechanism for Railway-Cars,of which the following is a full, clear, and exact description,reference being had to the accompanying drawings, forming a part hereof.

My invention has relation to improvements in fan-driving mechanism forrailway-cars; and it consists in the novel construction and arrangementof parts more fully set forth in the specification, and pointed out inthe claim.

In the drawings, Figure 1 is a side elevation of a car with parts brokenaway, showing my invention applied thereto. Fig. 2 is a verticaltransverse section on line 2 2 of Fig. 1. Fig. 3 is a verticaltransverse section on line 3 3 of Fig. 1. Fig. 4 is a horizontal sectionon line 4 4 of Fig. 2. Fig. 5 is a vertical section on line 5 5 ofFig. 1. Fig. 6 is a vertical section on line 6 6 of Fig. 5, showing thebeltpulley, however, in its disengaged position; and Fig. 7 is aperspective showing the pocket or cavity for the reception of thelocking-bar and its handle;

The object of my invention is to provide a railway-car with suitablegearing which may be coupled to the axle of the car-truck for thepurpose of driving a fan or fans within the car, thereby dispensing withthe use of electricity, steam, air, or other expensive means for thepurpose.

In detail the invention may be described as follows:

Referring to the drawings, C represents a conventional railway-car.Mounted on the axle of one pair of wheels of preferably the front truckis a cylinder or pulley 1, with which frictionally engages a belt-pulley2,pro-

, vided at one end with a peripheral groove 3 for the reception of themain belt 4. The axis of the pulley 2 is mounted on a yoke 5, suspendedfrom brackets 6, secured to the floor of the car, said yoke beingsusceptible of a slight vertical movement on said brackets, saidmovement being permitted by the elongation of the slots 7 formed in theyoke, through which the bases of the brackets pass. The top of the yokeis provided with projecting stems 8, over which are coiled the springs9, the latter being interposed between the yoke and car-bottom and bytheir resiliency normally forcing the pulley 2 into frictionalengagement with the axle-pulley 1. Projecting from and swiveled to theyoke 5 between the stems 8 is a rotatable stem 10, which passes throughthe floor of the car, the upper end of the stem having passed looselytherethrough the locking-bar 11, which latter is provided with a handle12, which may be folded or tilted against the bottom of the pocket orcavity 13, cut in the floor of the car for its reception. On each sideof the cavity 13 are located the arched blocks 14, the ridges of whichare provided with depressions 15.

When the pulley 2 is in engagement with the pulley 1. the bar 11 restsat the bottom of the cavity 13, parallel to the blocks 14, and

the handle 12 is folded down between the said blocks. To disengage thepulleys, the porter or brakeman picks up the handle; and by giving it aturn at right angles to its original position the ends of the bar 11ride up the inclined opposite ends of the blocks, thus raising the yokeand compressing the springs 9, and when the bar 11 is at right angles tothe blocks 14 the ends thereof will rest in the depressions 15 of saidblocks, thus holding the pulley 2 permanently out of engagement, Fig. 6.When thus disengaged, of course no rotation is imparted to thebelt-pulley 2 by any rotation on the part of the axle-pulley 1.

The belt 4 leads rearwardly over a-pulley 16, mounted on a shaft 17,mounted in brackets 18 at the bottom of the car, said shaft beingprovided with a grooved pulley 19, from which leads through the floor ofthe cara belt 20, which is crossed when the car is running in onedirection and which is open when the car is running in the oppositedirection, so as to always impart rotation in the same direction to thefan F in the car. When the belt is open, one of the laps passes over anidlerpulley 21. The top of the belt 20 passes over a pulley 22 at theend of a parallel shaft 23, near the roof of the car, the opposite endof the shaft carrying a pulley 24, from which passes forwardly a belt25, properly guided to the pulley 26 of the fan-shaft, wherever thelatter may belocated. I do not, of course, wish to limit myself to theprecise location of the fan nor to the number of them.

As seen from the dotted position of the parts in Fig. 4, the trucks inpassing over a curve do not materially affect the engagement between thepulleys 1 and 2. Of course the fans can only operate while the car is inmotion or during the trip. At the end of the trip there is no occasionto have the fans in operation, and if during. the journey it becomesdesirable to stop the fans a disengagement between the pulleys l and 2may be effected in the manner above described.

Having described my invention, What I claim is 7 In a car, a pulleymounted on the axle of the car-truck, a spring-controlled reciprocatingyoke depending from the bottom of the car, a belt-pulley carried by theyoke and normally forced into engagement With the axlepulley, a stemswiveled to the yoke and projecting through the floor of the car, alockingbar rotatably mounted at the upper end of the stem, arched blocksdisposed on each side of the stem on the floor of the car, the rotationof the stern causing the ends of the bar to ride up the inclines of theblocks and disengage the pulleys, the blocks having depressions formedat their ridges for receiving the ends of the locking-bar, substantiallyas set forth.

In testimony whereof I afiix my signature in presence of tWo Witnesses.

SAHAG TERZIAN.
